A new species of sandperch is described from the shallow nearshore reefs of the Masoala Peninsula, northeastern Mada-gascar. The new species is distinguished from congeners occurring in the region by a unique pigmentation pattern on thecaudal fin comprising two large, oblong black blotches, with the smaller of the two markings located dorsally near the finbase and a much larger and more elongate patch situated ventrally, as well as the presence of numerous smaller blackblotches forming two to three bands distally on the caudal membrane, two longitudinal series of six to nine prominentblack blotches on the mid and lower flank, and the presence of large diffuse dark brown blotches on the snout, lips, cheek and opercle.

Paretroplus loisellei, a new species of etropline cichlid from Madagascar, is described from the middle to lower reaches of the Mahanara River, located to the north of the Masoala Peninsula in northeastern Madagascar. The new species is recovered within the “Paretroplus damii clade” on the basis of several apomorphic anatomical features, including the presence of a triangular, black or dark gray, pectoral-axil patch, chest scales that are greatly reduced in size and highly embedded, and flank scales in which the posterior field is thin and unossified. The new species is distinguished from its sister taxon, P. damii, by a more or less horizontal profile extending from the anterior margin of the lower jaw to the ventroposterior margin of the suspensorium (vs. strongly rounded and convex), horizontally oriented oral jaws with fleshy lips (vs. oblique and thin), tricuspid symphyseal teeth in the upper jaw with distinct and sharp lateral cusps, a much darker overall pigmentation pattern, and distinctive bright golden breeding coloration (vs. brick red).

The new species Impatiens otto-eleonorae Eb.Fischer & Rahelivolona from Masoala Peninsula is described. It is related to Impatiens hildebrandtii Baill. from Eastern Central Madagascar, but differs in the larger habit and flowers. The types of Impatiens firmula Baker and I. hildebrandtii are reinvestigated. Both taxa, previously considered to be identical, represent different species, and Impatiens hildebrandtii is reinstated here.

Treefrogs of the genus Boophis comprise the most species-rich genus among all Malagasy frogs. In this paper we describe a new species to be added to this genus from Masoala Peninsula and nearby areas. Related populations have been found in three localities of North-Eastern Madagascar (Tsararano, Marojejy, and Anjanaharibe-Sud), and molecular data indicate that at least the Marojejy population is strongly differentiated. The new species has an attractive pink or reddish colour pattern on a green ground colour. It bears a strong similarity to Boophis bottae and B. rappiodes in morphological appearance, but is genetically very distinct from these and other members of the Boophis rappiodes group. Boophis ulftunni sp. n. belongs into a separate evolutionary lineage probably related to the Boophis microtympanum group, a lineage of highland species from Central Eastern Madagascar which otherwise have very different phenotypes and advertisement calls. We here include B. ulftunni in a new phenetic species group, the Boophis ulftunni group.

Characidium chancoense new species, is described from the transandean upper Río Cauca drainage in Colombia. It can be distinguished from all congeners by its pigmentation pattern that consists of 7–12 vertical bars, most of which are cuneate-shaped with the vertex ending on or just below the lateral-line scale series, except for the last 1–4, which are dorsoventrally elongate rectangular bars that extend well below the lateral line. Characidium chancoense is sympatric with C. caucanum Eigenmann, C. phoxocephalum Eigenmann, C. cf. zebra Eigenmann and C. cf. boavistae Steindachner. Unlike C. caucanum and C. cf. boavistae, C. chancoense does not appear to be sexually dimorphic.

A new species of ponyfish, Secutor mazavasaoka, is described from coastal waters of the Western Indian Ocean. Together, the new species, S. indicius, and S. insidiator are readily distinguished from congeners by more or less oval-shaped elongate bodies (vs. markedly deep and disk-shaped). The new species is distinguished from S. hanedai by the presence of scales on the chest (vs. chest asquamate), and from S. indicius and S. insidiator by a deeper, hatchet-shaped body (vs. uniformly oval) and pigmentation pattern on the dorsal flank comprising eight to eleven well-defined columns of irregular small spots and blotches (vs. 14 to 17 thin columns of spots or vertical lines in S. indicius, or larger irregular blotches arrayed in poorly defined columns in S. insidiator). Additionally, the new species is distinguished from S. insidiator by a strongly upturned mouth and compressed pug-like snout, a pronounced concavity dorsal to the orbit, a dorsally-projecting nuchal spine, and dorsal-fin insertion well posterior to vertical through pectoral-fin base (vs. at about level of pectoral-fin base in S. insidiator).

The Lake Malaŵi genus Melanochromis included five species at its inception and was originally distinguished fromPseudotropheus on the basis of morphology, including the arrangement of teeth on the lower pharyngeal bone. Thediagnosis has been extended twice, first to include all elongate mbuna that possess horizontal stripes and U-shaped toothbands and later to exclude mbuna that do not exhibit a sex-related reversal in their colour pattern. Recently, the diagnosisof the genus was refined on the basis of the melanin pattern. The genus now includes only species with a basic melaninpattern, which consists of two black horizontal lateral stripes on a light background. Most adult members of the genus,thus defined, have a sex-related reversal of pigmentation pattern. Here we describe Melanochromis mpoto n. sp. from thenorthwestern part of Lake Malawi, synonymize M. parallelus Burgess & Axelrod 1976 with M. loriae Johnson 1975,redescribe M. chipokae Johnson 1975 and M. robustus Johnson 1985, and reclassify and designate a lectotype for M. brevis Trewavas, 1935.

Pimelodus luciae is described from rio Itacaiunas, rio Tocantins basin. The new species exhibits a unique spotted pigmentation pattern for Pimelodidae. Pimelodus luciae differs further from remaining valid Pimelodus species by the following combination of characters: the relatively short distance between the posterior nostril and the anterior orbital border; dorsal surface of the supraoccipital process rounded; horizontal orbital diameter greater than interorbital distance; and distal portion of dorsal fin hyaline. Pimelodus luciae is known only from the type-locality.

Apareiodon agmatos, new species, is described from the upper Mazaruni River and its tributaries, Essequibo Basin, in western Guyana. The new species is distinguishable from all other species of Parodontidae by having an incomplete lateral line. The scales of A. agmatos are more numerous than in any previously described parodontid. It has five incisorlike pedunculate teeth on the premaxilla aligned in a straight row, each with a large central spatulate cusp bordered on each side by a minute lateral cusp. The maxilla has two or infrequently three incisors. It shares an unusual pigmentation pattern of one dorsomedial and four lateral black stripes with A. gransabana, which was described from the neighboring upper Río Caroní drainage, Orinoco Basin. Apareiodon agmatos also shares with A. gransabana and Parodon guyanensis a higher number (5 versus 4) of teeth than other members of the genus in the premaxillary. Apareiodon agmatos and A. gransabana may also share an absence of thickening of the anterior pleural ribs noted by Starnes & Schindler (1993) for A. gransabana. While beyond the scope of this work, these features may prove sufficient to diagnose this group of species from the genus Apareiodon as currently recognized.
